Application le c'tooer le', wm.

and State of New York, has invented ncrv and useful Improvements in Birection la dicators, oi which the following is a specifii cation.

The object of the invention is to provide l@ a. relatively simple and efficient sinnallingA means for use in connection with automobiles and similar vehicles whereby the intentions of the driver of a. car equipped therewith in the matter ci changing the diw rection oir forward progress or et stopping,l

or reducing the speed oi progress may be indicated to the driver out a following' vehicle under such conditions as to avoid the danger of rear-end collisions and the like; and with d@ this object in view the invention consists in a construction and combination parte of which a preferred embodiment is shown in the accompanying drawings, vrhereint Figure l is a side view partly broken away 25 of a vehicle equipped with a signalling mechanism embodying1 the invention.

Figure 2 is a rear vievv oi 'the saine.

Figure le is a horizontal sectional vievv oli the Seriel No. 507,905.

Figures l5 and 16 are detail views in perspective of the adjacent ends of the lampv box to show the means for securing' the same in closed relation.

The signalling device proper is supported on the rear end of the cer body which is indicated in the drawings at 10 by means of upright bars 11 connected by a transverse frame l2 consisting* of spaced angle bars which are connected near their extremities by segmental brackets 13 provided With slots i4, and the lamp boxes 15 which are c0nstructed as indicated in detail in Figures l2, i8 and 1li are mounted upon said brackets through the medium of angle bars i6 held in place by bolts 17 which extend through the slots i4 and slots i8 in said angle bars to the end that the lamp bones may be adjusted angulariy on the supporting frame to occupy a substantially horizontal position or a horizontally facing position regardless of the inclination or under cutting of the rear side of the vehicle body. The apparatus is thus adapted tor application to a variety ci diilerent terms and makes ci car The lamp boxes oi which one is arranged at each end of the supporting traine adjacent to each side of the car body., contains a plurality of ligflitingg1 units such as the lamps i9 and is provided with a. cover 20 preferably hinged as at 2i and having" a slotted ear 22 'at its tree end for registration with a corresponding1 ear 23 on the box proper tor the reception of a lockiinrp bolt @d to secure the same in its closed position. This lamp bor: cover bears the signalling symbol which in the construction illustrated is represented as an arrow 25 protected by a glass or other light penetrable medium 26 and visible only when the lighting` units are in use. The closing oit the circuit through the lamps' in one signal bor.' thus will indicate the intention ot the driver to turn to the lei-t While the lighting of the units in the other bor *will indicate an intention to turn to the right `While the illumination ci both signals will indicate an intention to stop or reduce the progress and thus serve as a warning; to the driver of a i'ollovving" car to avoid attempting to pese the car ahead Vlhe means for actuating or selectively illuminating the signal bones consists in the construction illustrated ot keys 27 pivotally dii lli

mounted as at 28 in suitable su ports 29 depending from a bracket 30 w 1ch ma be supported on the dashboard of the ve 'c le within convenient reach of the drlyer, said keys being yieldingly held by springs 31 in' their normal positions and carrying contacts 32 for engagement with stationa contacts 33 to respectively close the circuits through the conductors 34 with the lamps in the respective lamp boxes. A n indlcator or check lamp 35 is preferably arranged in each circuit controlled respectively by the keys,

so that when a key is operated the lighting of the correspondingr check lamp 35 serves as a means of showing that the signal is properly operating at the rear ofthe car.

ny suitable source of energy such as the battery indicated at 36 may be employed in the signallingT circuit of which a diagram is indicated in Figure 7 and which indicates the Having described the invention, what is claimed as new and useful is :fv

1. A device for the purpose indicated comprising a transverse frame having uprights terminally attachable to a vehicle body on the rear end, signal boxes carried at the remote ends of the frame, and brackets on the frame for supporting said boxes and an larl adjustable to horizontally position sai boxes.

2. A device for the purpose indicated comprising a transverse frame, signal boxes carried at the remote ends of said frame, u rights supporting the frame and terminally attachable at their extremities to the rear end of a vehicle body, segmental brackets carried by the frame, angle bars pivotally secured to said segmental brackets, the latter being provided with spaced slots concentrically arranged with respect to said pivot points, and bolts passing through said angle bars and selectively engageable 1n lsaid brackets for horizontally positioning the boxes irrespective of the angle of inclination of the vehicle body.

In testimony whereof he ailixes his signa ture.
